Abstract

This paper introduces Least Mean Square (LMS) based calibration technique for Voltage Controlled Oscillator (VCO) based ADC. The VCO provides an inherent sinc filtering for the input voltage. The harmonics are also attenuated by the corresponding sinc functions. An 8-bit VCO based ADC was simulated with a 5-bit linear VCO. This ADC was calibrated using LMS algorithm. After calibration, SNDR is close to the ideal 8-bit converter.
